Diodes
This circuit can be built to test how a simple diode works. Rectification
This is the simplest rectification circuit you can build. The output wave looks like this:
The rectified potential is known as half-wave rectification. [Click >> to see the output potential] The addition of a filtering capacitor smoothens out the rectified potential.
This is a full-wave rectification that uses four diodes.
Here is another circuit that achieves the same type of full-wave rectification.
Look how a filtering capacitor smoothens out the direct current.
Light Emitting Diodes (LEDs) are used in signal devices for timing purposes.
